Here is the sample

Hello Psky,

Sorry for the delay. You should make small modification in protected override Infragistics.Win.CalcEngine.UltraCalcValue Evaluate() method. I used our previous sample and I made changes in this method. Using a LINQ you could get desired results. For example:

var w = Rows.Where(z => z.Index <= gg && z.GetCellText(z.Band.Columns[0]) == FilterValue).Sum(s => Convert.ToDecimal(s.GetCellText(col)));

Please take a look at the attached sample for more details and let me know if you have any questions.

Regards
